Pakistan International Airlines Flight 688 was a domestic passenger flight from Multan to Islamabad with a stopover in Lahore, operated by Pakistan's flag carrier Pakistan International Airlines. On 10 July 2006, the aircraft operating the route, a Fokker F27, crashed into a mango garden after one of its two engines failed shortly after takeoff from Multan International Airport. All 41 passengers and four crewmembers on board were killed. Pakistan Civil Aviation Authority (PCAA) attributed the causes of the crash to multiple factors. One of the engines started to malfunction during the take-off roll due to improper assembly. Despite the aircraft being able to stop within the remaining runway distance, the pilots opted to continue their take-off. They failed to carry out the correct emergency procedure and as a result the airspeed rapidly decayed, ultimately stalling the aircraft. Aircraft The aircraft was a Fokker F-27 registered as AP-BAL with a serial number of 10243. The aircraft was manufactured in February 1964 and was delivered to Pakistan International Airlines in 1979. According to the logbook, the aircraft had a total flying hours of 73,591. The engines were produced by Rolls-Royce. The left engine and the right engine were manufactured in 1959 and 1958, respectively. Both engines had been overhauled at the PIA Ispahani Hangar facility approximately one year prior to the crash. Passengers and crew The aircraft was carrying 41 passengers.
